Non-Custodial Key Management
for DeFi
Smart contract wallets carry execution risks. MPC threshold signing eliminates the single point of failure in key management — without requiring users to manage seed phrases.
The challenges your team faces.
Smart contract wallet risks
Account abstraction and smart contract wallets introduce execution layer vulnerabilities. A bug in the contract is a bug in the custody model — affecting all users.
Seed phrase UX kills adoption
Requiring users to manage 12-24 word seed phrases creates friction and support overhead. Most DeFi users have experienced seed phrase loss or theft.
Single point of failure in key management
Browser extension wallets, hot wallet signers, and centralized key stores all create single points of failure — unacceptable for institutional DeFi flows.
Cross-chain key management complexity
Different signing schemes (ECDSA on EVM, EdDSA on Solana/TON, Schnorr on Bitcoin) require separate key management for each ecosystem.
MPC threshold signing
for institutional DeFi.
MPC 2-of-3 Threshold
No single private key ever exists in one place. Signing requires 2 of 3 parties — eliminates any single point of failure at the cryptographic level.
Policy-based signing rules
Define allowed contracts, spending limits, and chain restrictions per wallet. Agents and users can only execute what policy explicitly permits.
All signing schemes
ECDSA (EVM), EdDSA (Solana, TON, NEAR), Schnorr (Bitcoin). One MPC framework covers all major chain ecosystems.
API-native integration
Connect your dApp or DeFi protocol to MPC wallets via REST. Users get non-custodial security without managing seed phrases themselves.
